Re: Yoga 920 USB C to HDMI not working

2018-01-03, 21:27 PM

All,

 

Thank you for your patience and valuable information provided in this thread, the efforts expended in finding a possible solution by different individuals is also greatly appreciated.  I've been informed that the driver teams have been working on this issue in order to provide a resolution, they have also confirmed that which some members have stated; the cause is a driver conflict at system level with Redstone 3 the 1709 Creators Update.

 

I'll update this thread with any new information I receive along with the solution's expected release date as and when I am informed.

 

Thank you again

 

Andy

Re: Yoga 920 USB C to HDMI not working

I've been able to get the USB C-HDMI adapter working by installing a fresh windows 10 vers 1703. But after installing windows 10 vers 1703, the fingerprint reader not working. Anybody else has had this issue? It keeps saying windows found synaptic driver but unable to install code 31.

Re: Yoga 920 USB C to HDMI not working

The USB-C to HDMI issue has being my only issue with the Yoga 910.

 

I am a teacher and this is a big issue for me for presentations.

 

My girlfriend is looking for a new laptop and right when I recommend her the Yoga lineup I get this issue again...

 

Looking forward to a fix!

The 910 HDMI does not work the same as the 920 HDMI as the 920 has two Thunderbolt ports to 910's single port. Therefore, anything that improves 920 performance will probably have no impact on the 910.

Other than my 920, I also have a 910. On the 910 I have windows and drivers on automatic update and just don't have an HDMI problem with it. If I were you, I'd start with updating the drivers and applying windows updates to get them all current.
(I am assuming you are using the forward USB-C port and not the back port.)

Re: Yoga 920 USB C to HDMI not working

Been looking for a new laptop to replace my 2015 mac pro, was all ready to push the button on a 920 when I saw the HDMI issue in the forums. Using multiple monitors is critical to me when I work from home.

 

I was wondering while waiting for lenovo to pull their fingers out and fix the driver issue has anybody else tried replacing the graphics drivers with the stock intel ones and had rock solid results with it. I see someone had mentioned it previously and it working for them but no-one else appears to have done so yet?

I'm now able to connect to an external display at will with no odd sequencing of connections and/or restarting.

 

You've been VERY silient here Lenovo... but thanks for finally fixing things.

 

FYI - I'm using this adapter:

After waiting and struggling for 24 days, I returned shipped my Yoga 920 yesterday.

 

Now Lenovo decides to chime in on the conversation and admit a problem and that a resolution is being worked on.  Arggh! very poor customer service.  Could have spoken earlier so everyone could have stopped wasting their time and would have known that its now a known issue that is being worked on.

FINALLY!

 

I sa the new Firmware pop up this morning and immediately installed it. When it said it had to do with reconfiguring the USB-C adapter I was grinning ear-to-ear. Installed, rebooted, and grabbed every previously failed USB-C to HDMI adapter I had (4 different ones). The results?

 

drumroll please.....

 

EVERY SINGLE ADAPTER WORKS! YES!

 

I even hot-swapped between TV's and monitors. ZERO issues. I feel like I got a brand new laptop today. THANK YOU for fixing this issue Lenovo!
